type-c-service: Migrate to async function calls

[RobertZ2011]

• Remove bridge code and last bit of messaging
• Final move away from Context type, application code is now responsible for creating event senders/receivers
• Remove almost all GlobalPortId usage

Pull request overview

Refactors the Type-C service from a centralized Context + Bridge-based messaging architecture to direct async method calls on locked port objects. The Type-C service now operates over a generic Registration trait that exposes ports as &[&Port] and uses per-port event channels plus a new event receiver abstraction.

Changes:

• Delete the bridge module and the service::context::Context request/response indirection; the service now calls Pd/UcsiLpm trait methods directly on locked ports.
• Introduce service::registration::{Registration, ArrayRegistration} and service::event_receiver::ArrayEventReceiver; require port traits (Pd, Retimer, Controller, Lpm, SystemPowerStateStatus) to be Named.
• Carry a port reference (&'port Port) in PortEvent/Event instead of GlobalPortId, and split Event from EventData.
